Abstract

A RECEIVER (400) IN A COMMUNICATION SYSTEM IS OPERATED BY RECEIVING A RADIO COMMUNICATION SIGNAL TRANSMITTED BY A STATION OF THE COMMUNICATION SYSTEM AND GENERATING A CORRELATION OUTPUT REPRESTING A CORRELATION OF THE REICEIVED RADIO COMMUNICATION SIGNAL AND A SUBSEQUENCE OF A MODULATION SEQUEENCE AND THE MODULATION SEQUENCE. THE RECEIVER IS THEN SYNCHRONIZED BASED ON THE GENERATED CORRELATION OUTPUT. THE SELECTED SUBSEQUENCE PREFERABLY HAS AN OPTIMAL OUT-OF-PHASE CORRELATION WITH THE MODULATION SEQUENCE. ACCORDING TO AN ASPECT OF THE PRESENT INVENTION, THE SELECTED SUBSEQUENCE HAS A MINIMUM OUT OF PHASE CORRELATION WITH THE MODULATION SEQUENCE IN COMPARISION TO OTHER SUBSEQUENCES OF THE MODULATION SEQUENCE. FOR EXAMPLE THE SELECTED SUBSEQUENCE MAY HAVE A "MINIMUM MAXIMUM" OUT-OF-PHASE CORRELATION VALUE, A "MINIMUM AGGREGATE" OUT OF PHASE CORRELATION METRIC OR A COMBINATION THEREOF.FIG.4
